Considering how closely fans scrutinize every single minute detail, I’m flummoxed as to why it’s escaped my attention that Allison Janney will guest star on”Lost” two weeks from tonight? Titled “Across the Sea,” the 15th episode in the show’s final season will reportedly completely explain FLocke’s true motives.

In the press release, Janney is simply listed as “woman” while Mark Pellegrino and Titus Welliver are back as Jacob and man in black, respectively. So their inclusion doesn’t really shed much light on which timeline her character will be a part of — or why an actress of Allison’s caliber would take a one-off guest spot as a nameless, insignificant character.

My best bet is that “woman” will be one of the many mysterious faces who will come to play some sort of integral role — and get a name — as the final episodes click down.

And for those of you who are thinking, “well there must be a million Allison Janneys out there,” a rep for ABC confirms to PopWrap that it is, in fact “that Allison Janney.”
